Abstract: Example manual wheel restraint systems and methods for restraining a vehicle at a loading dock include are disclosed herein. An example wheel restraint disclosed herein includes a retractable wheel-blocking barrier mounted to a carrier that can be repositioned along a track, where the track is anchored to a driveway of a loading dock. The track runs generally parallel to a vehicle path that a wheel of a vehicle travels along as the vehicle backs into the dock. To block a rear wheel of the vehicle parked at the dock, the barrier extends laterally into the wheel path, adjacent or in front of the wheel. To release the vehicle, the barrier retracts out from within the wheel path. In some examples, to ensure that the vehicle is secured, the barrier and/or the carrier include barrier or carrier catches to help hold the barrier and carrier in a fixed position. In some examples, one or more sensors determine or sense whether the catches are secured or released and generate signals accordingly.

Abstract: An example wheel restraint includes a track to be positioned adjacent a vehicle approach path of a loading dock. A shuttle is pivotally coupled to the track via a track follower and pivots between a home position and a deployed position about a shuttle axis substantially parallel to and offset relative to a longitudinal axis of the track. A barrier is pivotally coupled to the shuttle and pivots between a non-blocking position and a blocking position about a pivot axis substantially parallel to and spaced apart from the longitudinal axis of the track such that the shuttle rotates in a first direction about the shuttle axis when the shuttle moves from the home position to the deployed position and bather rotates in a second direction about the pivot axis when the barrier moves from the non-blocking position to the blocking position, where the first direction being different than the second direction.

Abstract: An example wheel restraint includes a wheel chock that is manually movable between a retracted or release position clear of a wheel of a vehicle at a loading dock and an operative position to block the path of the wheel. In the release position, the chock can be manually moved freely along a track that is mounted to a driveway of the dock. When the chock is manually moved from its release position to its operative position, a locking feature automatically restricts the movement of the chock relative to the track. When the chock is manually moved back to its release position, the locking feature automatically disengages. Although the wheel chock is connected to a track, much of the force exerted by the wheel against the chock can be transmitted directly from the chock to the driveway.

Abstract: Wheel restraints for restraining vehicles at loading docks are described herein. An example wheel restraint includes a restraining arm to anchor a wheel chock to a fixed point at the dock. When in a blocking position, the chock rests directly upon the dock's driveway without the chock having to engage additional hardware that could be an obstruction to snow removal. In some examples, the wheel chock automatically swings between its blocking and release positions in response to the arm simply lowering or raising the chock.

Abstract: Vehicle restraint systems are disclosed herein. An example vehicle restraint system includes a base to be positioned adjacent a loading dock and a wheel chock to be positioned on the base. An actuator is coupled to the base and moves the base relative to a wall of the loading dock in a linear direction between a release position and a holding position when the wheel chock is coupled to the base. In the release position, the wheel chock disengages from a wheel of a vehicle positioned at the loading dock. In the holding position, the wheel chock frictionally engages the wheel of the vehicle to restrict movement of the wheel away from the loading dock.

Abstract: A wheel restraint for restraining a vehicle at a loading dock includes various features such as, a wheel chock supported by a spring loaded articulated arm with a spring that can be selectively tightened or released, a sensor that detects whether the chock is solidly against a base plate or floor, a bi-directional pivotal joint between the articulated arm and the wheel chock to ensure that the chock can sit squarely on a mating base plate, a wheel chock that meshes with a hydraulically actuated base plate, pivotal or otherwise movable backstops that prevent a wheel chock from sliding out of position, and a base plate cleaning system. The cleaning system might include a vehicle-actuated brush, fluid spray nozzles, electric heater and removable cover plates.

Abstract: A wheel restraint for restraining a vehicle at a loading dock includes a flexible elongate member with one end that can be manually wrapped at least partially around at least one of the vehicle's wheels. The other end of the elongate member is connected to an anchor that is generally fixed relative to the dock. The anchor preferably includes a reel for taking up slack in the elongate member. When the restraint is not in use, the reel can take up and store the elongate member. The restraint preferably provides a signal that indicates whether the wheel is actually restrained. The restraint might also include a wheel chock coupled to the elongate member. A floor-mounted guide can help prevent interference between the elongate member and certain parts of the vehicle.
